    CAUTION: Be sure all solenoids are installed with the electrical connectors facing the non-machined (cast) side of the valve body; otherwise, the solenoids will bind against the transmission case as the valve body bolts are tightened and damage may occur.
  1. Install the 1-2 and 2-3 shift solenoids.
  2. Install the 1-2 and 2-3 shift solenoid retainers.

  4. Connect all the internal wiring harness electrical connectors to the electrical components (1-6).
  5. Install the 1-2 accumulator. Refer to Accumulator Assembly, Spacer Plate, and Gaskets .
  6. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement .
  7. Fill the transmission to the proper level with DEXRON® VI transmission fluid. Refer to Transmission Fluid Check .
    8. NOTE: It is recommended that transmission adaptive pressure (TAP) information be reset.
    Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, the engine control module (ECM), powertrain control module (PCM) or transmission control module (TCM) will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
  8. Reset the TAP values. Refer to Transmission Adaptive Functions .
